Abstract (en)

[origin: WO2017093304A1] Aluminium alloys suitable for etched and anodized components, in particular aluminum extrusion alloys of the types containing Magnesium and Silicon, which after being extruded to any wide variety of forms for different applications such as house buildings and other building applications is subjected to etching in a conventional alkaline etching bath and subsequent anodizing, wherein the relation between Cu and Zn is controlled to avoid preferential grain etching and the ratio of Cu/Zn is below 1.
